I'd love to hear the pros/cons of filtering adult content at the DNS resolver level. I'm assuming the (current) lack of whitelists, along with a black-box algorithm to decide what constitutes adult content, reduces the usefulness.
- JdeBP 7y agoThe pros are obvious. The cons, irrespective of what is blocked, are very similar to the problems with DNS hijacking that ISPs and others have done over the years. It affects all protocols, not just HTTP(S). It affects everything from turning IP addresses in logfiles into domain names, through double-reverse-lookup checks in TCP services, to SMTP electronic mail. Block advertising this way, and one hits the further problem that one often wants to operate based upon more than just the domain part of the URL. Or one wants to do things like make temporary redirects to static placeholder images. Fiddling with DNS service cannot achieve these. * http://jdebp.uk./FGA/verisign-internet-coup.html http://jdebp.uk./FGA/verisign-internet-coup.html
